Specification of Letters Patent.

Patented APT..1, 1919*.

Application filed June 5, 1918 Serial No. 238,249.

To all whom it may concern:

Be it. known that I, WILLIAM. GEO GE AN ERS a ubject of the King of Gr at Britain and Ireland, residing at Whitehead, county 'Antrim, Ireland, haveinvented certain new and usef l Improvement n Toy Building-Blocks,:of which the following is a specification.

This invention relates to toy building blocks with which models of houses, buildings, and the like, canbe built froma number of blocks, or pieces, its object being to provide improvements in blocks of the class having interlocking tongues and grooves, for example, such as described in the specification of my prior United States Patent Number 1236896. 1

Under the present invention I provide corner pieces and pieces adapted to extend between parallel walls to tie same, comprising interlocking pieces the pieces :having each, on the upper and under sides, a longitudinal tongue and a transverse groove which is cut at least twice as deep as the tongue. The transverse grooves are cut at such distance from the .end of the block and to such depth that, when the pieces are interlocked at right angles, the tongue of the one piece engages-the groove of the other piece so that the outer sideoif the. one piece is flush with the end of the other piece. The corner pieces havea transverse groove at one end only while binding pieces, or. tie-pieces", between parallel walls have the transverse grooves at both ends Of the piece.

The tongues and grooves of the pieces cooperate to bind the pieces together when an upper piece is piece, so that pieces in any vented.

movement of the interlocked horizontal direction is pre- Binding and .tie pieces,-as above described, pleces for wallsyor may be used as parapet as eaves pieces for roofs, or they may be made to form any other desired finish to, or part of, a wall. They may also, if desired, be made with their tongues and grooves terminating short of their ends and sides and engaging with. corresponding pieces, having their tongues and grooves also terminating as described, so that the tongues and grooves will be concealed when the pieces are in position on or in, the wall.

Starting or finishing, or base, or parapet pieces, or other pieces, may have the invention applied to one upper or under side only superimposed upon a lower of the piece, and the other side may be solid or may have a longitudinal groove and (or) a transverse groove, according to the nature of the piece with which it is to be engaged.

In order that the inventionmay be clearly understood I have hereunto appended two explanatory sheets of 'drawings'whereon I have shown some examples of my improved interlocking corner blocks and binding b cks Figure 1 shows an isometric view of the interlocking. corner blocks in accordance with my invention and also shows a binding or tieipiece and an eaves piece made under the invention.

Fig. 2 is an isometric view showing the interlocking corner blocks in position and showing how the tongues and grooves of the under blocks are concealed at each side of the corner.

Fig, 3 is a similar view to Fig. 2 but with two cornerblocks shown in position for intellQcking.

Fig, 4 is a view of another modification of tie piece and eaves piece in which the tongues of the blocks are concealed at the side of the wall. 7

Figs. 5 and 5 'are detail side elevation and plan view respectively of one of the corner p ec s, hown in Fig. l- Figs. 6'and 6 are respectively end elevation and. plan of the corner-piece shown in Figs. 2 an 3 and showi g a double g o piece connected therewith, and superimposed ona tie. piece.

Referring to the drawings z+ Corner piece a and pieces 6, adapted to extend'between parallel walls to tie same, have each .on .thezupper and under sides a longitudinal tongue c and a' transverse groove cl which is cut at least twice'as deep as the tongue, the transverse grooves Z- bei-ngeut at such distance from the end of the blocks a or I), as the case may be, that when interlocked at right angles with either pieces a or b, the tongue of the one piece, for example a will engage the groove of the other piece 6 so that the outer side of the piece a will be flush with the end of the piece I). The corner pieces a have a transverse groove (Z at one end only while the binding pieces, or tie pieces, Z), for binding parallel walls, have the transverse grooves (Z at both ends of the piece. (See Fig. 1.)

The tongues and grooves cooperate to bind the pieces together when an upper piece'is superimposed upon lower pieces, as shown at Fig. 5, and the corner pieces cooperate with double grooved wall pieces f and double tongued wall pieces 9 which fill in between the corner pieces. The grooves f of thepieces f are engaged by the tongues g of the next course of wall bricks g, the pieces 7 and 9 being used in alternate coursesin building a wall. The use of corner pieces as "described prevents movements of'the' interlocked pieces in any horizontaldirection.

Binding and" tie pieces 6 as above described may be used, as in the example shown, as" eaves pieces 76 for roofs, or they may be made to form any other desired finish to, or part of, a wall.

The corner pieces, such as al and tie pieces, vsuch as 6 may be made with a groove (Z inone side of each block instead of across the top'and bottom of the block, andwith their tongues terminating short of their ends, as shown at Figs. 2, 3, 4, 6, and 6i, and engaging with corresponding pieces, having their tongues terminatingand grooves made as described, so that all the tongues and grooves will be concealed when the pieces are in position on, or in, the wall.

. Starting orfinishing or base, or parapet pieces, or other pieces, may have the invention applied to one side only of each piece,

as shown by the bottom blocks f and g or Figs. 2 and 3 where the grooves and tongues are on'the top side only, the bottom being solid.

. Having now fully described my inventi'on, what I claim and desire to secure by Letters Patent is I 1. For use in building toy houses and buildings, interlocking blocks for uniting the walls, having on their upper and under sides a longitudinal tongue and a transverse groove.

2. For use in building. toy houses and buildings, interlocking blocks for uniting the walls having on thelr upper and under sides a longitudinal tongue and a transverse groove the depth of the groove being equal to the height of the tongue.

3. For use in building toy houses and buildings, interlocking blocks forming corner pieces for uniting the walls havingon their upper and under sides a longitudinal tongue and a transverse groove, the groove being formed at such a distance from the end of the block that when blocks are superposed and interlocked at right angles, the outer side of one block is flush with the end of another block.

4. For use in building toy houses and buildings, interlocking blocks forming corner pieces for uniting the walls having on their upper and under sides a longitudinal tongue and a transverse groove, the groove being formed at such a distance from the end of the block that when blocks are superposed and interlocked at right angles the tongue of one block engages the groove of another block to bring the outer, side of the one block flush with the end of the other block.

5. For use in building toy houses and buildings, interlocking blocks forming corher pieces for uniting the walls having on their upper and under sides a longitudinal tongue and on the inner side of the block a transverse groove, the tongue terminating short of the end of the block, the groove being formed at such a distance from the endof the block that when blocks are superposed and interlocked at right angles, the tongue of theblock engages the'groove of another block to bring the outer side of the one block flush with the end of the other block.

6. For use in building toy houses and buildings, interlocking blocks each having a pluralityof longitudinal tongues and a plurality of transverse grooves the tongues and grooves terminating short :of the ends and sides of the blocks.

In testimony whereof I afliX my signature in presence of two witnesses.
